Definitions

  • Suitable solvents or diluents for use in the reaction of the compounds Ill and IV are, for example, benzene, nitrobenzene, toluene, dichlorobenzene, chlorobenzene and dimethyl formamide.
  • Suitable basifying agents are, for example, tertiary amines, such as triethylamine, tripropylamine, ethyl diisopropylamine, pyridine or potassium carbonate.
  • the starting materials Ill and IV are conveniently used in stoichiometric amounts.
  • Anthraquinone derivatives containing nitro groups are, following the reaction with the compounds of formula IV, reduced or reacted with amines by usual methods in order to convert the nitro group to an amino group or to substituted amino group.
  • reduction may be carried out in solvents, such as dimethyl'formamide, N-methyl pyrrolidone, dichlorobenzene, glycol ethers or water, at temperatures ranging from 20 to 100 C. and beneficially from 30 to 60 C., with reducing agents such as sodium sulfide, hydrogen sulfide, sodium dithionite or hydrazine.
  • Reactions with amines may be carried out, for example, in the solvents listed immediately above at temperatures ranging from 100 to 170 C.
  • novel dyes are valuable disperse dyes for use in dyeing and printing synthetic textile materials such as fibrous materials made from polyester or polyamide fibers.
  • the dyeings and printings thus obtained are characterized by good fastness to light and to cracking and by good thermal fastness properties.
  • the novel dyes are also useful as pigment dyes and are suitable, for example, for the mass coloration of thermoplastic synthetic resins as also for the dope-dyeing of polyesters and polyamides.
  • the textile materials are dyed and printed with the novel dyes by the usual methods.
  • Dyeing is carried out with dyebaths which conveniently contain the dyes in dispersion. Using such dyebaths, dyeing is carried out at temperatures between 95 and 100 C. at ambient pressure, or at temperatures above 100 C. by the high temperature process or the thermosol process. If it is desired to produce strong colorations at temperatures near 100 C., is is convenient to add a carrier.
  • For printing polyester and polyamide fabrics use is made of printing pastes containing the said dyes in finely divided form together with the usual thickening agents and printing auxiliaries. It is convenient to add carriers to the printing pastes also. Very good results are also obtained when mixtures of the novel dyes are used.
  • EXAMPLE 1 16.6 parts of 1-amino-4-nitroanthraquinone-Z-carboxylic acid chloride in 150 parts of nitrobenzene and 1 part of triethylamine are heated with 6.8 parts of benzamidoxime at 15 C. for 2 hours. The mixture is allowed to cool and is then filtered. The solid residue is suspended in a solution of 18 parts of sodium sulfide (60%., flaked) in 300 parts of water and 4 parts of n-butyl, alcohol. After 2 hours at 80 C. the precipitate is filtered off and dried in vacuo at 50 C.
  • EXAMPLE 2 16.6 parts of l-amino-4-nitroanthraquinone-Z-carboxylic acid chloride and 8.2 parts of 2,5-dimethylbenzarnidoxime are heated in 150 parts of nitrobenzene and 1 part of triethylamine for 2 hours at 150 C. The precipitate is filtered ofi and dissolved in 130 partsof N-methyl pyrrolidone and parts of tripropylamine. Hydrogen sulfide is then passed through the solution for 3 hours at 30 to 40 C. The mixture is cooled and the precipitate filtered off and dried in vacuo at 50C. Yield: 16 parts of the dye of the following formula (melting point 300 to 302 C.):

After cooling, the precipitate is filtered off and dissolved in parts of N- methyl pyrrolidone and 75 parts of tripropylamine. Hydrogen sulfide is then passed through the solution for 2 hours at 30 to 40 C. The mixture is cooled and filtered, and i4 parts of the dye of the following formula (m.p. 282 to 285 C.) are isolated as solid residue:

After cooling, the precipitate is filtered off, dissolved in 80 parts of N-methyl pyrrolidone and 10 parts of tripropylamine and reduced to the blue dye of the following formula by passing hydrogen sulfide through the solution at 70-80 C:
